Amy Bel Marlowe: Pseudonym for the Stratemeyer Syndicate
The Stratemeyer Syndicate was founded by Edward Stratemeyer and is best known for producing the Bobbsey Twins, Hardy Boys, Nancy Drew, Rover Boys, and Tom Swift series. The Syndicate produced these and many other series in assembly-line fashion: one person wrote the outline for a story or series of stories, another wrote the story itself, and often still another edited the work. Most Syndicate books were published under pseudonyms. The authors named in this list are those credited as having written the series; in most cases, the names are fictitious.
Edward L. Stratemeyer (October 4, 1862 – May 10, 1930) was an American publisher and writer of children's fiction.
